Q

often fossil fuels are extracted from sedimentary rock that lies underwater which means that spills during extraction, like those caused by broken pipes, directly pollute the surrounding water and destroy local aquatic ecosystems.

Q

the falling water rotates the blades of a _________, which then spins a generator that converts the mechanical energy of the spinning turbine into electrical energy

A

Turbine

17
Q

The size of the reservoir created by a hydroelectric project can vary widely, depending largely on the size of the hydroelectric generators and the topography of the land

A

LAND USE

18
Q

constructing large storage or pumped storage hydropower plants involves blocking, diverting, or changing the natural course of the river system

A

Wild Life Habitats

19
Q

hydroelectric facilities can still have a major impact on aquatic ecosystems. It changes the concentration of nutrients, water temperature, and the river’s flow

A

AQUATIC ECOSYSTEMS

Q

the most common way for adult fish to get past a dam is to use a fish ladder, a water-filled structure that allows fish to pass up and over in a series of steps

A

FISH LADDER

21
Q

at dams and places where it is not practical to install a fish ladder, a trap and haul operation can be used to move adult fish upstream

A

TRAP AND HAUL

22
Q

the most unusual form is an experimental “salmon cannon” — developed with DOE support — that can shoot adult salmon over a dam through a tube.

A

SALMON CANNON
